Abstract

PURPOSE: To clarify the clinical and radiologic parameters that can be used to differentiate odontogenic keratocyst and ameloblastoma
MATERIALS AND METHODS
The records of 46 patients of ameloblstoma and 48 patients of odontogenic keratocyst at the Yonsei University Dental Hospital during the period of 1979 to 1995 were retrospestively reviewed. As a possible means for differentiating between the odontogenic keratocyst and ameloblastoma, the clinical parameters and the radiologic parameters were evaluated.
RESULTS
In the clinical parameters, there was no significant defference in age, sex, and sign and symptoms(p>0.05).In the radiologic parameters, there was significant difference in site, shape of the lesion, and external root resorption of adjacent teeth(p<0.05).
CONCLUSION
The site, shape of the lesion, and external root resorption of adjacent teeth can be the parameters to differentiate odontogenic keratocyst and ameloblastoma, but a definite differentiation of these two lesions needs a more specialized imaging modality.
